1" 'o of? whom "it may concern:

lie 1t lcnown that l, Jon's HOWARD Ross,

subject of the King of Great Britaii'nrcsiding at 17 Gordon road, lilandsworth, Staffordshire, England, have invented certain new and useful Improvements in Acetylene-Gem erators, of which the following is a specification. I

This invention relates to improvements in acetylene generators for lamps and the like, i

and its object is to provide improved means whereby to maintain, practical y, an uniform head of water above the point at which it is led to the carbid, in order to insure a more uniform pressure and supply of gas to varymg requirements.

The primary feature of my invention is, the employment in the manner hereinafter described and shown, of fixed and moving pipes, of a more or less telescopic charactcr-in connection with the water su )ply mechanism of such generators, and in which the supply is discharged from the upper part of the moving pipe, the movement of the said pipe being effected by its being connected to, or operated by, a suitable movingpart in the generator. 1 attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows this my invention as applied to an acetylene generator, in which ar rangemcnt the expansible carbid container,

is utilized as the means for operating the supply pipe. Fig. 2 shows this my invention as applied to an acetylene ,gcnerator, in \\'ll1(l1 arrangement a moving float carried at the 3 head of the water is utilized as the means for operating the supply pipe. Fig. shows this my invention as applied to an acetylene generator, in which arrangement a movable gas reservoir is utilized as the means for operating the supply pipe.

Similar numbers of reference apply throughout to the same thing or part.

I do not confine myself to the precise dej tails in carrying out this my invention, inasmuch as it will be readily seen that in each of the cases shown and described some of the details differ from the others, but at the same time it will be seen that the essential feature of my invention, viz., the arrangement and operating of the fixed and moving pipes is alike in each case.

Referring to the arrangement as shown in reference to Fig. 1 :-5 is a movable. Pipe having its lower end closed, saidpipe being oarried or supported from the interior wall 6 f of the carbid container (5 by means of the flange 7 which is secured to the pipe 5 resting upon the top of the wall 6. The upper side 8 of this flange 7 is the point at which the deliveryof water to the carbid takes place.

9 is an interior pipe which is of a fixed character, by being secured to the bottom of the water reservoir 10.

11 represents the water which inc-y pass through the holes 12 into the pipc S1 and thence to the pipe 5. The carbid container is supported. by the spring 13.

14 is the gas reservoir the contents of which may be delivered for consumption through the pipe 15, to the burner 16.

17 is a valve which under the pressure from the spring 18 always tends to closeupon and shut off the water from the pipe 9. This valve may be opened and retained open as illustrated, by means of the rod 18: having side projections 20, which may be lowered into the cross recesses 21 (shown in. dotted lines) for closing the valve, and raised and turned at right angles so as to rest upon the upper surface 22 in order to open said valve. 1 The action of this device is therefore as 1 follows: 'l.he height or head of water reprosented by reference number 22% having been determined according to the intruded delinand upon the generator, that is to say, when the generator is in working, the norl inal pressure of the gas will sufficiently rcsist the inflow of water so as to maintain that head. The valve 17 is opened, when the water will pass down the inner pipe 9 and rise exteriorly thereto in the pipe .5 uni til it o erflows at S passing thence to the i carbid dirough the holes :24. (his is immediately generated which passes into the chamber 14, and at the same time die rarbid expands and forces its container downward j against the spring 13, and consequently the delivery point 8 is correspondingly lowered, ]whieh lowering,when the apparatus has i assumed its proper working will coincide with the lowering of the water at 11, and I thus maintains an uniform height. As hei fore intimated the valve 17 may be closed when the generator is not required. It will further be seen that the valve 17 serves also as a safety valve, inasmuch as should the gas in the chamber 14 become excessive 'hile the valve 17' is open, it will force back i the} Water and find its way readily to the atmosphere through the space between the bush and the rod 19. Even should the valve be shut, the said excessive pressure would raise the valve 17 and permit the escape of the gas. T he lower part of the generator is closed by any suitable door or the like 26 secured in any convenient manner.

Reterring now to the arrangement as illustrated in Fig. 2, the pipe 5 is connected to the moving float 27 by means of the rod 28 and the yoke 29. The fixed pipe 9 1s secured to thebottom 10 of the water reservoir by means of the upstanding cylinder 30. The water shut oli valve in this caseis shown at 31, controlling the inlet thereat to the interior of the fixed pipe 9. This valve can be opened or closed by the screwed end 32. The action in this case is briefly as follows: The head of water 23 is arranged as before described. The valve 31 is opened, and the water passes as before down the pipe 9 and thence up the pipe 5, and over its end 8, flowing therefrom to the carbid through holes 24.

As the water level at 1] is lowered, so also is the float 27 lowered, and with it of course the overflow point 8 of the pipe 5, thus maintaining an uniform head of water pressure.

It will also be here noticed that in case 0g excessive gas pressure, the water will b driven back through the pipes 5 and 9 as before described, and escape through the top of thelatter.

Referring now to Fig. 3, it will be seen that substantially the same arrangement exists as in the two previous cases except as to the moving bodyutilized to operate the pipe 5.

In this case the pipe 9 is secured to the upright cylinder 30 which is part of the water reservoir 10, and whose upper end is closed except at the central opening of the pipe 9. 33 is the gas holder, its interior forming the gas chamber 14. The pipe 5 is connected to the end stop 34, between which and the top of the cylinder 80 is disposed the spring 35,

which tends always to close the upper end of the pipe 5 against the interiorof the cylinder 30, or the bottom against the lower end of the pipe 9 toact as a valve, and thus com-- pletely shut oil the water ,supply. In'this case the carbid container 6 is conveniently made to pass horizontally into position through the doorway at the side when the door 26 is removed. Its action is therefore as follows: arranged as before described. To initially start the apparatus the tap 15 is opened, when the withdrawal of gas (if there is any in the holder) permits the said holder 33 to descend until the stop 34 slightly depressed by the top of the holder 33, by which the upper end or point 8 of pi e 5 is lowered so that the water can pass t ence to the carbid, when gas is generated and passes into the chamber 14. So long the as is at or below the normal pressure, the older 33 rests on and controls the stop 34, by which the end 8 of the pipe 5 is maintained at the predetermined height, and as the water at 11 is lowered so also the holder 33' is lowered and the point 8 is correspondingly lowered; Should however the pressure in the chamber 14 be increased beyond demand, or the tap 15 closed, the holder will rise and leave the stop 34, so that the spring 35 will then lift the pipe 5, and thus cut off the supply of water. Further, in case the pressure 111 chamber 14 becomes excessive the lower end of the inverted pipe 36 will be raised above the upperend of the pipe 37, when the gas will at once freely escape through said pipe to the atmosphere without further raising the holder.

What I claim as my invention and desire to secure by Letters Patent is: v
